IMPROVEMENT IN WOOD-PAVEMENTS.

Specification forming part of Letters Patent No. 123,219, dated J annary30, 1872.

To all whom it may concern:

Be it known that I, GEORGE A. BEIDLER, of Philadelphia, in the county ofPhiladelphia and in the State of Pennsylvania, have invented certain newand useful Improvements in \Vood Pavement and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying dr wing and to the letters of referencemarked thereon making a part of this specification.

The nature of my invention consists in a wooden pavement composed ofwedge-shaped blocks cut or sawed away at each end near the base to forma tenon and shoulder, and resting upon strips or scantlings laidlengthwise with the street, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a perspective View of a portion of the pavement, and Fig. 2is a perspective view of one individual block.

A A represent the wooden blocks, having their sides beveled so as to bewider at the base than at the top; or in other words, made wedgesha-ped.At each end, near the base, these blocks are cut or sawed away to form atenon, a, with a shoulder, I), at each end. The blocks A A rest withtheir shoulders b I) upon strips or scantlin gs B B, which are laidparallel with each other and suitable distance apart to receivebetweenthemthe tenons cc of the blocks. These strips or scantlings runlengthwise with the street and not across the same. When the blocksbreak joints a central transverse groove must also be cut in the bottomof the block.

By this mode of laying the supporting-strips the pavement can be madewith very little, if any, trouble to form the necessary curve of thestreet; and, when necessary to take up any part of the pavement for thelaying or repairing of gas and water pipes, etc, it can be done veryreadily the whole length of the street, and only so much in width as isnecessary to dig downone, two, or three rows of the blocks.

I may Burnetizc or otherwise prepare the blocks and the strips topreserve the wood. The spaces between the blocks are to be filled withgravel, sand, tar, or pitch, concrete, or any other suitable material.

I do not claim a wedgeshaped block; nor do I claim wedge-shaped blocksprovided with grooves on their sides, through which strips are passedcrosswise of the street for securing the blocks in place; but

What I do claim as new, and desire to secure by Letters Patent, is-

The wedge-shaped block A cut or sawed away at each end near the base toform a tenon and shoulder, and resting upon the strips or scantlings Blaid lengthwise with the street, substantially as and for the purposesherein set forth.

Intestimony that I claim the foregoing I have hereunto set my hand this11th day of November, 1871.
